there are bad touch screen systems and there are good ones. just as there are badly laid out physical controls and good ones.
even muscle memory works with touch screens, to say otherwise is just a lie. however the biggest oversight people tend to ignore is, how little they actually interact with controls of their car other than the turn signals and such. Most modern cars have full climate controls which does include humidity and such, many have automatic lights and wipers, and some go as far as doing the driving.
nineteen to twenty four buttons on steering wheel is just fine and intuitive to some just like the same number on a center console yet these same people will complain about the simplicity of a properly design touch UI and fewer physical buttons as being too complex.
